Well, thanks to the folks at USA Today, we have absolute confirmation of this by way of some leaked images. And goodness, she's certainly a looker.
While a few of us still find some of the 4 Series' design to be a bit awkward, it's hard to not immediately warm up to the aggressive bits of this hotter M4 concept. It certainly looks the business of a proper sports car, and a worthy successor to the M3 coupe. Of course, a lot of this will likely be toned down for the production version, which we'll likely be seeing at the 2014 Detroit Auto Show in January, along with its four-door BMW M3 kin.
The official M4 Concept details will be revealed later tonight, but for now, have a look at a few shots of the golden show car in our gallery of leaked shots, above.
